In one bit of good news, following a recent update, the "Live TV" app now does respond to digits sent via ECP! These can be sent using the Android app's (and presumably iOS too) keyboard entry mode, although having to peck at numbers on the top row, rather than having a proper numeric pad isn't ideal.
For times when I have a laptop next to me, I wrote this simple shell script to control the Roku TVs via ECP. Anyone using it will need to at least adapt the device names and IPs (static DHCP bindings on your router are a good idea), but this could be a good starting point.
Sample commands:
$ ktv 7 (will send 07.1, filling in .1 if no subchannel's given; leading 0 helps it tune faster)
$ ktv 47.1
$ ktv - (recall / last-channel: swap current & previous channel tuned via this script)
$ ktv yt https://www.youtube.com/watch?v=wSP2RWWATr8
$ ktv mute
(see script for more; all remote keys are recognized, and more channels can be added easily using IDs revealed by the "apps" argument)
